All you cynics who thought Prison Break was coming back just to cash in on our nostalgia... think again.

Sarah Wayne Callies told press including Digital Spy that she wouldn't have signed up to reprise her role of Sara Tancredi if money was the only motivator.

"It matters to me that we do this well," she insisted. "The reason that I was the last cast member to sign on is because I wanted to make sure that we were doing this because there was a really great new story to be told - not because somebody at Fox thought that they could make a lot of money.

"I have a job [on USA series Colony], I work on a show that I love. We all have other jobs. We're all on other shows. So I only want to come back to this if we have something to say - and I think we do."

Callies admitted that she feels a "responsibility" to deliver a top-quality revival that matches Prison Break at its best.

"The fanbase for the show is as loyal to us as Michael (Wentworth Miller) and Lincoln (Dominic Purcell) are to each other," she said. "...and that's a beautiful thing, but it also feels like it confers a responsibility, to deliver something to them that's worthy of their love.

"It was a joke, but I turned to Dom before we shot the first scene and I was like, 'Let's not f**k it up!'."

Prison Break will return to Fox in 2017, airing on Tuesday nights at 9/8c.
